BIFFI PHW Power Hand Wheel series

The BIFFI PHW Power Hand Wheel series has been engineered and

manufactured to provide easy and quick operation ofpipeline valves

equipped with a gear reducer instead of the operation of turning

manually the gear reducer's hand-wheel.

GENERAL APPLICATION

Power Hand Wheel Unit is designed for theoperation of linear and quarter

turn valveson pipelines where power source (Electric,Pneumatic,

Hydrauliclis not available.

FEATURES

• Anodized aluminium body and coversprovides light weight together with

compactoverall dimensions.

• Simplicity of construction and ease of useare at the top of design and

constructionparameters.

• High torque and speed performance.

• All gearing running in the oil bath whichallows global high and constant

efficiency andlow power consumption.

• Manual operation by hand-wheel withengagement lever an automatic

disengagementin case of motor rotation. The handwheel doesnot rotate

when motor is running.

• Local indication of valve position by a devicemechanically connected to

the valve stem or,upon request, local dial indicator or remoteindication by

electrical switches

• Weatherproof as standard (IP 68 according toIEC 529]

• Explosion proof protection available in caseof requirements for electrical

components(limit switches, position transmitters,solenoid valves, etc)

• Mechanical stops available on request.

• Supply connections with quick connectorsand protecting Plugs
